What you’re noticing: The treadmill feels like it “stutters” or runs unevenly.

Try this:

1) If the incline support is raised to the highest position:
At very low speed (slow walking), a slight stuttering sensation can be normal. (If your model does not have an incline support, please ignore this.)

2) If the incline support is NOT raised and the belt stutters under load (or won’t move):
Check these in order:

If you’ve tried everything above and the stuttering is still obvious (or the belt still won’t move), the motor may be faulty. Motor replacement isn’t a DIY repair—please contact support for the right next step (return/exchange service).

Try this:

If you just added lubricant:
Stop adding lubricant. Use a lint-free cloth to absorb some excess lubricant from both sides/edges of the belt, then test again.

If you did NOT add lubricant:
Follow the user manual to tighten the running belt appropriately.

It depends:

If the belt is centered with no one on it, but shifts when you walk/run:
This is usually not a treadmill defect. Please check:

• Whether the treadmill is level on the floor
• Your walking/running posture (consistent stepping)

If the belt is off-center even with no load:
Please refer to the belt alignment adjustment video and adjust until the belt runs centered.

Check in this order:

1) Safety key
Make sure the safety key is seated in the correct spot.

2) Power switch indicator light
See if the power switch indicator is on.

If none of the checks above help, please contact support for return/exchange service.

A quick guide:

Normal operating sound
A steady, even sound from the motor/rollers/moving parts is normal.

“Clicking” sound (first use or after storage)
This can happen after unboxing or long periods of non-use because the belt stiffens. Let the treadmill run with no one on it for up to 1 hour. The sound should fade out over time.

If the noise sounds clearly abnormal:

Still happening? Please record a short video of where the sound is coming from and contact support.

Check these:

• Remove the motor cover and make sure the belt isn’t rubbing the upper/lower motor cover.
• Check whether the motor is rubbing the lower cover. If so, add spacers/washers after confirming no debris is causing friction.
• Make sure wires aren’t touching the fan, and nothing inside the motor cover is contacting the flywheel/pulley/belt.

If the noise is coming from the motor itself, the motor may be damaged. Please contact support for return/exchange service.

Try this:

• If you have a thermometer/temperature gun, measure the temperature. Up to 158°F during operation is generally considered normal.
• Figure out where the heat is coming from: usually the running belt/deck or the motor area.
• Make sure the motor bottom ventilation holes aren’t blocked. If you’re on carpet, raising the incline support (if applicable) can help airflow.
• Also check the motor top cover temperature. If it’s extremely hot to the touch, the motor may be abnormal—please contact support.

Try this:

• Make sure there’s enough space around the treadmill for ventilation—especially the motor bottom ventilation holes.
• Check if the running belt is rubbing against other parts (side rails, rear cover, motor covers). If it is, adjust the belt until it runs without contact.
• If it smells like burning from the front motor area and the motor cover is very hot, the motor may be faulty—please contact support for return/exchange service.

What it usually means: E01 is a wiring/connection issue, often caused by vibration during shipping.

How to fix it:

• Open the control panel.
• Look for any connectors that are loose.
• Push them back in firmly and tighten if needed.
• Restart the treadmill and see if the code clears.

If it won’t clear, please contact customer support.

What it usually means: E07 relates to the safety key—typically the treadmill isn’t sensing it correctly.

How to fix it:

• Confirm the red safety clip/cord is attached correctly, then power on again.
• If it’s attached correctly, try using another magnet at home and place it on the treadmill’s designated sensor area (the yellow-marked area) to see if the error disappears.
• Follow the E07 troubleshooting video guide (external link) for step-by-step help: Insert link

Still seeing E07? Contact support to request a replacement safety key (if applicable).

What it usually means: E05 indicates a motor fault or abnormal communication between the motor and control board.

How to fix it:

If the treadmill and motor look normal but E05 remains, it’s likely a controller/control board issue—please contact support to request replacement parts. If none of the above resolves it, support will recommend the best after-sales solution (repair/return/exchange depending on the case).
